The Mavs won their first National Basketball Association championship in June. A lockout began in July, as NBA owners and players negotiate a new labor agreement.

Mark Davenport, a lawyer for Perot, said his side was still considering whether to appeal Smith’s decision.

“Right now, we’re looking at all our options,” he said.

In the lawsuit, filed in May 2010, Perot’s side alleged that the Mavericks were insolvent and asked a judge to appoint a receiver to manage the team’s finances.

Perot sold a controlling stake in the Mavericks to Cuban in 2000, but he retains a 5 percent interest.

Last month, Smith granted a request by Cuban’s lawyers to seal certain financial documents about the team. Perot is appealing that ruling, arguing that the documents should be public record.

In a court filing by the Perot side last week, some general financial information appeared about Dallas Basketball Ltd., which does business as the Mavs. Other portions were redacted.

“In the 11 years since Mark Cuban purchased the majority interest in DBL, DBL has lost more than $335 million, or an average of more than $30 million per year,” the filing said.

“These are not merely ‘paper’ losses,” it added. “Over that same period, DBL has had negative cash flow from operations of more than $240 million. To fund these losses, DBL has been forced to borrow approximately $250 million.”

The filing called the team “hopelessly insolvent,” and argued that Cuban may one day decide “that he cannot feed the cash-eating machine he has created forever.”

Melsheimer declined to comment on the team’s finances.

“I can say that Perot’s lawsuit challenged the financial health of the team,” Melsheimer said. “And the court, by granting summary judgment, rejected all Perot’s claims.”

In July 2009, Perot filed a lawsuit against Cuban alleging mismanagement in the partnerships that control American Airlines Center. At the time, Cuban accused Perot of “trying to find nickels in the sofa cushion.” That suit was dismissed earlier this year after arbitration last year.
